From: Sustainable agriculture in the era of omics: knowledge-driven crop breeding
Breeding crops for sustainable agriculture. a Strategies to improve current varieties with the knowledge gained through omics data. b An example to show increase in gain yield and decrease in nitrogen input when two genes (NGR5 and GRF4) were introduced into the original variety [7, 8]. GRF4, growth-regulating factor 4; NGR5, nitrogen-mediated tiller growth response 5. c An example to illustrate changes in plant architecture which makes it suitable to cultivate under urban environment by knocking out three genes [10]. sp, self pruning; sp5g, paralog of sp; er, erecta
